Teams with defenses that project to be in the NFL’s upper tier, as the Broncos expect theirs to be, often make developmental life tough on quarterbacks in training camp practices.

Broncos offensive coordinator Adam Gase monitors how the quarterbacks are doing in practice to see if they need to dial things back a bit to get some momentum.

“We try to let them be aggressive, but if you are having one of those practices where there are a lot of incompletions going on, (quarterbacks coach) Greg Knapp does a great job of letting them know that we need to get some completions,” Gase said. “Everything is situational, so we give them a down and distance every play. So, if it is second-and-3 and we’re calling a shot play and it’s not there, we’ll tell them to get to the check-down. Make sure we get to first down and move on.

“Once we start getting completions, then that guy’s confidence starts to build and he’ll get a little more aggressive and take a shot down the field.”
